Define problem
I'd say organised crime is a problem yes.
There's better approaches. I've seen more coke use in London and Chester than Liverpool (though I've also seen coke taken loads of places including before our games at Anfield)
I don't really think it's anyone's business what someone does with their body as long as they don't hurt anybody else. Though I wouldn't be surprised if cocaine is behind some town violence.
I'm pro decriminalisation but if I wish one drug was around a lot less, it would be cocaine. A stupid drug with no long term benefit. Even ketamine has a future, like psychedelics, in therapy.
When most people talk about drug problems though it tends to be "someone annoyed me in a pub by being loud or disgusting".
Whereas the biggest problem I've personally seen lately is a recurring problem of those little laughing gas canisters... Outside the infants' school. Over and over. I kick em down the drain if I pass. But like, keep this crap away from children!
The real drug argument though is why people take them and the societal issues causing it. They're an escape.
